Garrett Delfosse 378ac91b49 fix: stem chat search terms with the english text search config (#28319)
Chat message search used the `simple` text search config, which folds
case but does no stemming, so `refactor` did not match messages
containing `refactoring`. Message bodies now index and query with the
`english` config, which stems both sides. Titles, PR titles, and all
other filters are unchanged.

Migration `000585` adds a `chat_messages.search_tsv_config` enum column
recording which config produced each stored vector and stamps existing
vectors `'simple'` (a column-only update; vectors and indexes are
untouched, since rewriting `search_tsv` would block message writes on
large tables). The dbpurge sweep gains a bounded
`ReindexStaleChatMessagesSearchTsv` pass that rewrites stale vectors
newest first and stops for the process lifetime once drained. Until a
row is rewritten, `GetChats` matches it with the config that produced
it, so pre-migration exact-form searches keep working during the drain.
Vectors written by old binaries mid rolling upgrade cannot stamp the
config, stay pending, and self-heal on the next upgraded sweep.
Steady-state DB load is unchanged.

The down migration resets `english` vectors to `NULL` so the parent
version's existing sweep rewrites them with `simple`.

<details>
<summary>Decision log</summary>

- **`english` stemming over prefix matching.** On a 300k-row corpus a
stemmed lookup is a single GIN entry-tree probe, while `term:*` prefix
matching unions posting lists of every lexeme sharing the prefix (up to
a full scan for short prefixes), is asymmetric, and loses the
`websearch_to_tsquery` phrase/OR/negation UX. `pg_trgm` rejected as a
heavier index with different semantics.
- **Scope to message bodies only** (review). Titles and PR titles keep
their `simple` FTS expressions and indexes, identical to main.
- **Config-versioned queue over migration-time reset** (review). An
unqualified `UPDATE ... SET search_tsv = NULL` rewrites every indexed
row in the migration transaction, and an old replica could backfill
reset rows with `simple` vectors that permanently leave the `search_tsv
IS NULL` queue. The config column makes staleness explicit and both
problems disappear.
- **Enum over `text`** (review) for the config column.
- **Trade-offs.** English stopwords are dropped from message search
(stopword-only queries match no messages); stemming is English-specific;
titles do not stem; prefix matching remains out of scope.

Jaayden Halko 511dcc0293 feat(coderd/x/chatd): bill interrupted tool batches on cancellation rows (#28362)
**Stack**: #28359 → #28360 → #28361 → **#28362 (this PR)**

## Summary

Interrupted local tool batches now bill the partial window they actually
executed, recorded on the same dedicated usage record completed batches
use. Completes the runtime billing work in this stack: completed batches
bill via #28360, interrupted batches via this PR.

Last of a four-PR stack splitting #28211. Stacked on #28361. Closes
CODAGT-928
(https://linear.app/codercom/issue/CODAGT-928/track-local-tool-execution-for-agent-runtime).

## Problem

Interrupting a batch previously billed only the model window; work the
tools already performed was lost.

## Fix

Just before closing the buffer episode, the interrupt task reads the
live tool stamps (`ToolCompletions`) alongside `ModelInvokedAt`. The
interruption commit appends the shared `batchUsageMessage` record (same
shape as #28360: model-only tool-role row with a
`billed_ms`/`billed_calls` audit payload) billing the union of the
started, billable calls' partial execution intervals: completed calls
end at their recorded completion, running calls at the interrupt
instant. Synthesized cancellation rows stay free of batch-level runtime.
Unstarted calls, rejected calls, and sub-agent orchestration tools bill
nothing and append no record. Batches with no live attempt (crash
recovery, state promotion) bill nothing, consistent with generation
losing in-flight runtime on a crash.

Usage-record billing reuses the same interrupt instant as the model
window instead of taking a second clock reading inside the transaction,
so database delay cannot inflate a running call's window.

An earlier revision carried a retry-stable episode snapshot so an
interrupt retry after buffer eviction (a >15s stall) would not lose
billing; it was dropped as not worth the complexity
(https://github.com/coder/coder/pull/28211#discussion_r3812778418). Such
a retry now bills the batch at zero, matching the existing
crash-recovery precedent.

Known gaps left out of scope: retry backoff and errored-attempt time
stay unbilled (no persistence home for error turns), and the advisor
tool's nested model call now bills as tool time by design.

Jaayden HalkoandHugo Dutka 64d2d8a108 feat(coderd/x/chatd): record live tool execution stamps in the message part buffer (#28361)
**Stack**: #28359 → #28360 → **#28361 (this PR)** → #28362

During local tool execution, buffer episodes now record when each
tool-call occurrence actually starts and finishes, via
`RecordToolStart`/`RecordToolCompletion`/`ToolCompletions` on the
message part buffer. Occurrences are keyed by unresolved-call position,
so gaps left by rejected calls and duplicate tool-call IDs stay
distinct: `partitionAmbiguousToolCalls` additionally returns the allowed
calls' input positions, and generation's `chatloop.ToolBillingRecorder`
implementation translates dispatch-order stamps back through them.

Mechanism only: nothing reads the stamps yet. The final PR in the stack
uses them to bill interrupted tool batches on a dedicated usage record
committed alongside their synthesized cancellation rows.

Michael Suchacz cc958b73be fix(coderd/x/chatd/mcpclient): enforce MCP connect budget and unblock session cleanup (#28400)
## Problem

During the Aug 19 dev.coder.com incident, chats stalled for up to ~15
minutes per turn. chatd reconnects to every configured MCP server on
every generation step, and one configured server
(`registry.coder.com/mcp`) was black-holing requests from the
deployment's egress IPs: TCP/requests were silently dropped, and each
connect attempt hung until the kernel gave up (~125s), far past the
nominal 10s connect budget.

The budget does not hold because go-sdk v1.7.0 detaches the context
inside `StreamableClientTransport.Connect`, and its error paths block on
HTTP work bound to that detached context. Reproduced in a test: a bare
`Connect` with a 2s deadline against a black-holed server returns after
**12s**. Step-end session cleanup (`session.Close()`) runs synchronously
in the generation loop and blocks on the same detached requests, so a
server that wedges mid-turn stalls every step boundary too.

## Changes

- **Enforce the connect budget externally** (`connectOne`): run
`Connect` + `ListTools` in a goroutine and select on the budget context.
On timeout, abandon the goroutine and leave a reaper that drains its
late result and closes any session that still materialized, so nothing
leaks and the caller returns within the budget.
- **Stop using bare `http.DefaultTransport`**: MCP traffic now rides a
cloned transport with a 5s dial timeout (converts SYN black-holes into
fast errors) and a 60s `ResponseHeaderTimeout`. `http.Client.Timeout`
stays unset so long-lived SSE streams are unaffected.
- **Close sessions in detached goroutines during cleanup**
(`ConnectAll`'s cleanup func): the sessions are discarded regardless,
and a wedged `Close` (DELETE bound to the SDK's detached context) must
not stall the generation loop at step boundaries.

One deliberate deviation from the incident plan: `ResponseHeaderTimeout`
is 60s (matching `toolCallTimeout`) instead of ~10s. The same HTTP
client serves tool-call POSTs, and a JSON-response MCP server sends no
headers until the tool finishes, so a 10s bound would falsely kill
legitimate 10-60s tools that fit today's tool-call budget. The real 10s
connect budget is enforced by the external select, not the transport.

## Tests

- Acceptance: with a black-holed server plus a healthy one configured,
`ConnectAll` returns within the budget and the healthy server's tools
are present; closing the black-holed connections makes the reaper exit
(red without the fix: 1s budget took 11s).
- A slow-but-alive server (300ms/request) still connects.
- A server that only responds after the budget: `ConnectAll` returns
promptly, the late result is reaped.
- Cleanup returns promptly while the session-teardown DELETE is wedged
server-side, and the teardown still happens in the background (red
without the fix: cleanup blocked 60s).
- Transport guard test pinning the dial/response-header bounds.

`go test ./coderd/x/chatd/...` passes (including goleak in `chatd`).

Part of the MCP connect-stall incident follow-up; observability (connect
durations in logs/debug runs) comes in a stacked follow-up PR.

Jaayden Halko b428c8feb6 feat(coderd): bill completed local tool batches in agent runtime (#28360)
**Stack**: #28359 → **#28360 (this PR)** → #28361 → #28362

## Summary

Completed local tool batches now count toward Coder Agent runtime
(`chat_messages.runtime_ms`, the source of truth for
`hb_agent_runtime_v1`), excluding sub-agent orchestration tools to avoid
double counting, and without multiplying runtime for parallel tool
calls.

Second of a four-PR stack splitting #28211. Stacked on #28359. Refs
CODAGT-928
(https://linear.app/codercom/issue/CODAGT-928/track-local-tool-execution-for-agent-runtime).

## Problem

Agent runtime previously measured only model invocation wall clock
(stream open to fully consumed). Time spent executing local tools
between steps, including file operations, terminal commands, workspace
provisioning, and MCP tools, was deliberately excluded, which
undercounts the product definition of "actively processing a task".

Naive inclusion has two hazards: a batch of parallel tool calls would
bill N windows for one wall-clock wait, and `wait_agent` would re-bill
child agents that already bill their own model and tool time.

## Fix

Each completed local tool batch bills one window: the union of the
billed tools' execution intervals, persisted as `runtime_ms` on a
dedicated usage record appended after the batch's tool-result rows. The
record is a tool-role message with `visibility='model'`, so it never
reaches the API, SSE, or clients, and prompt replay drops it because its
single internal `tool-batch-usage` part converts to no provider content.
Its content carries an audit payload (`billed_ms`, `billed_calls`) so
the billed window is inspectable after the fact; real tool-result rows
never carry batch-level runtime. Concurrent calls all start at batch
start, so 5 parallel 10s reads bill 10s, not 50s; serial calls
(`SerialToolCalls`) count only from their own launch, so unbilled waits
before them do not count.

Sub-agent orchestration tools (`spawn_agent`, `wait_agent`,
`message_agent`, `interrupt_agent`, `list_agents`,
`list_subagent_models`, plus the deprecated `close_agent` alias) never
extend the window: every chat, including children, applies the same
rules to its own runtime, so a parent's `wait_agent` window would double
count. A lone `wait_agent` bills 0 and appends no usage record;
`execute` 10s in parallel with `wait_agent` 60s bills 10s. A test pins
the unbilled set to the registered sub-agent tool catalog so they cannot
drift.

`GetTotalChatMessageRuntimeMsInRange` already sums `runtime_ms`
role-agnostically, so the usage record is picked up with no schema,
query, or cron changes.

Client-executed dynamic tools, external agents, parked/idle time, and
retry backoff remain unbilled. Interrupted batches still bill only the
model window; the rest of the stack adds partial-window billing via the
same usage record.

`ExecuteLocalToolsOptions` also gains an optional `ToolBillingRecorder`
(`RecordStart`/`RecordComplete`) observing per-occurrence dispatch-order
execution stamps. This PR wires no recorder; the next PR in the stack
connects it to the message part buffer for interrupt billing.

**NOTE**: Reported agent runtime (`hb_agent_runtime_v1`) increases from
deploy forward. There is no backfill and no feature flag.

Michael Suchacz e244cac9c1 feat(coderd/x/chatd/chattool): improve find_tools relevance and model guidance (#28476)
Broad `find_tools` queries such as "linear issues" saturated the hard
20-match cap on every call: a large server's name token-matches every
one of its tools (+8 name, +1 server), so ranking was decided by a term
carrying no discriminating information and the model got 20 activations
per search regardless of intent.

Three changes, mirroring what makes xum's `tool_catalog_search` behave
well:

- **Lower default with a `limit` argument.** Keyword matches default to
10 per call; the new optional `limit` raises that up to the existing
hard cap of 20 (non-positive values fall back to the default). Exact
`names` are explicit activation requests and bypass the limit up to the
hard cap, so naming 15 tools still activates all 15.
- **Coverage-first ranking.** Keyword matches sort by distinct query
terms matched before raw score, so a query like "linear issues" ranks
tools matching both terms above the dozens matching only the server
name.
- **Model guidance.** `queries` and `names` now carry schema
descriptions (capability keywords and what they are matched against;
exact-name activation), and the tool description opens by explaining
what deferral means, that matches become callable on the next step, and
that a `"server: terms"` prefix scopes a query to one server.

An earlier revision also inferred a server scope from unprefixed query
words ("linear issues" behaving like "linear: issues"). Review kept
surfacing edge cases in that inference, and coverage-first ranking
already resolves the original saturation complaint, so it was dropped in
favor of the explicit prefix.

The hard cap stays at 20 so the persisted result keeps fitting under the
generic tool-result truncation budget that protects activation-recovery
JSON. Budget and reservation accounting are unchanged; the frontend
renderer ignores unknown argument fields, so no `site/` change is
needed.

`TestActiveServer_RetryStatePersistedDuringBackoff` advanced whichever
mock-clock timer was next while waiting for the retried provider call.
If the provider goroutine had not incremented its call count yet, the
test could advance the unrelated 15-minute task timeout and trigger an
extra whole-task retry.

Trap and release only the named generation-retry timer, then wait for
the provider call without advancing the clock again.

`ExecuteLocalTools` now returns the `PersistedStep` directly and the

Kyle Carberry cf97b56479 fix(coderd/x/chatd): refresh context after workspace restart (#28441)
Workspace lifecycle tools clear a chat's agent binding while retaining
its pinned workspace context. When the chat binds to the replacement
agent, the missing previous agent ID caused chatd to skip re-pinning and
continue using stale instructions, skills, and MCP definitions.

Re-pin when an unbound chat still carries pinned context, while
preserving the existing first-time hydration path for new chats without
a pin. Adds regression coverage for the stop/start binding sequence.

### CI note

All required checks pass. The external `Pixel / Review` status reports

Michael Suchacz b6d7653231 fix: apply MCP server selection when editing a chat message (#28471)
## Problem

Editing a user message in an Agent chat silently dropped the MCP server
selection. The composer renders the MCP picker in edit mode and toggles
update local client state, so the picker displayed the new selection,
but the edit request omitted `mcp_server_ids` at every layer (frontend
request builder, `codersdk.EditChatMessageRequest`, the `PATCH
/chats/{chat}/messages/{message}` handler, and `chatd.EditMessage`). The
chat's persisted selection never changed and the regenerated turn ran
without the newly enabled MCP tools. Two dogfood users hit this within
hours; there is no error anywhere and the UI shows the opposite of the
server state.

## Changes

- `codersdk`: add `MCPServerIDs *[]uuid.UUID` to
`EditChatMessageRequest`, mirroring `CreateChatMessageRequest` (nil
preserves the current selection).
- `chatd`: extract the send path's MCP update block into one shared
`applyRequestedMCPServerIDs` helper (explore-subagent snapshot
immutability guard plus Force On enforcement, Cure53 CDM-02-010) and
call it from both `SendMessage` and `EditMessage`, so enforcement cannot
drift between the two paths.
- `coderd`: extract the send handler's request validation (dedupe,
enabled-in-organization check, persisted-ID exemption) into
`normalizeRequestedChatMCPServerIDs` and wire it into the edit handler,
which now threads the selection into `EditMessageOptions`.
- Frontend: the edit request now includes `mcp_server_ids:
[...effectiveMCPServerIds]`, exactly like the send path, making the
picker's displayed state real.
- `make gen` artifacts (swagger, API docs, `typesGenerated.ts`).

## Tests

Each layer is covered and was proven with independent red toggles
(removing one layer's wiring fails only that layer's tests):

- chatd (`TestEditMessage_MCPServerIDs`): edit applies a provided
selection, nil preserves it, an emptied list cannot remove a `force_on`
server, and explore subagent chats keep the spawn-time snapshot.
- API (`TestPatchChatMessage/MCPServerIDsApplied`,
`MCPServerIDsInvalidRejected`): persistence via the endpoint, omission
preserves, unknown IDs get the same 400 as the send path.
- Storybook (`EditAppliesMCPServerSelection`): toggling a server on
during an edit puts it in the edit request payload.

Note: the `AgentChatPage.stories.tsx` story "Queued For Capacity After
Polling" fails locally on current main as well (verified against the
main baseline with this branch's changes reverted); it is unrelated to
this diff.

Remote dogfood UAT ran on the exact head and passed, including proof
that the regenerated turn actually gains the newly enabled MCP server's
tools.

Michael Suchacz a48aedd924 fix(coderd/x): surface Gemini malformed-function-call stream deaths as retryable errors (#28470)
## Problem

When Gemini's OpenAI-compatible endpoint rejects a model-generated
function call server-side, it ends the SSE stream cleanly with the
nonstandard finish reason `function_call_filter:
MALFORMED_FUNCTION_CALL` after streaming only thought summaries; the
rejected call never reaches the wire. chatd treated this as a normal
completion: fantasy maps the unrecognized finish reason to `unknown`,
the reasoning block never closes (the only non-thought delta is the
`</thought>` marker, which the transport seam strips to an empty string,
and the openaicompat hook only ends reasoning on a non-empty content
delta), so the step accumulates no content and the generation loop
finishes the turn as complete. The user sees the model think for ~40
seconds and then nothing: no assistant message, no `last_error`, chat
status `waiting`. Observed twice in a row in production on
gemini-3.7-flash, with "Resume" reproducing it identically.

## Fix

Two independent layers:

- `coderd/x/googleopenai`: the stream rewrite now converts any chunk
whose `finish_reason` starts with `function_call_filter` into an
OpenAI-style SSE `{"error": ...}` event embedding the raw reason.
openai-go turns error-bearing events into stream errors, so the failure
rides the existing stream-error path instead of ending the stream
cleanly.
- `coderd/x/chatd/chaterror`: classifies that injected error as
retryable (kind `generic`, provider `google`) with a clear user-facing
message, so the existing generation retry machinery re-runs the step and
persists a `last_error` if retries exhaust.
- `coderd/x/chatd/chatloop`: provider-agnostic guard: a step that
produced no user-visible content and no tool calls under a finish reason
of `unknown`, `error`, `other`, or `tool-calls` (a tool-calls finish
that delivered zero calls) now returns a retryable error instead of
silently completing the turn. `stop` and `length` finishes keep their
existing semantics.

Tests cover the seam rewrite (live-capture SSE shape plus standard
finish reason passthrough), the new classification, and the chatloop
guard (error cases plus preserved stop, length, text, and tool-call
behavior). Each layer was red-green verified independently.

Remote dogfood UAT ran against this exact commit: normal reasoning and
tool-call chats on a real model complete cleanly with no spurious guard
errors and no retry loops. The Google-side failure itself is not
deterministically triggerable against live Gemini and is owned by the
unit tests.

Cian Johnston 042421694f fix: surface duplicate AI provider hostname as warning, not error (#28208)
Two live `ai_providers` rows can share the same `base_url` hostname.
This is an intended configuration (AIGOV-97): the direct routing path
(`/api/v2/ai-gateway/{name}/...`) routes by provider name and fully
supports it. Only the MITM proxy path (`aibridgeproxyd`) cannot
disambiguate, because its `nameByHost` map is 1:1.

`classifyProviderRow` marked the second provider as
`ProviderStatusError`, which surfaced as a misleading log warning and a
`status=error` Prometheus label. The provider is not actually broken; it
is fully routable via the direct path. The error was only visible in
server logs and Prometheus, not in the API or UI.

This change:

- Extracts `BaseURLHostname` into `coderd/aibridged` and eliminates
three duplicate implementations (proxy classifier, chatprovider, and the
API layer now uses it for status checks).
- Downgrades the proxy classifier from `ProviderStatusError` to a new
`ProviderStatusProxyExcluded` status. The provider is not broken; it is
just not reachable via the MITM proxy path.
- Adds `Status *AIProviderStatus` to `codersdk.AIProvider` with
`Warnings []string`, matching the `WorkspaceProxy` precedent.
- Populates warnings on create, update, GET, and list when a provider's
hostname collides with another enabled provider.
- Adds an integration test proving that a duplicate provider is routable
via the direct path but not via the proxy path.

Michael SuchaczandEthan Dickson 0ef331fcd0 feat!: scope chat model override settings to organizations (#28442)
Moves chat model override settings from deployment scope to organization
scope, following the org-scoping of chat model configs in #28440.

Depends on #28440 (based on
`ethan/chat-models-availability-consolidation`).

Remote dogfood UAT passed on this change, including multi-organization
scenarios on a licensed deployment with real models.

## Problem

Chat model configs are now owned by organizations, but the override
settings that reference them stayed deployment-wide: admin
subagent/title/compaction overrides in `site_configs`, personal
overrides in `user_configs`, and the advisor model embedded in the
advisor runtime JSON. A single deployment-level override can only point
at one organization's model config, so overrides effectively worked for
the default organization only, and title generation had to soften its
hard-failure contract to tolerate unusable overrides.

## Fix

Admin overrides (general, explore, title generation, compaction,
advisor) and personal overrides (root, general, explore) become
organization-scoped rows in two new typed tables,
`chat_organization_model_overrides` and `chat_user_model_overrides`.
Composite foreign keys on `(organization_id, model_config_id)` make
cross-organization model references unrepresentable. The migration
deletes the legacy serialized `site_configs`/`user_configs` override
keys instead of migrating them; admins and users re-select models in the
new organization-scoped settings.

New endpoints live under
`/api/experimental/organizations/{organization}/chats/model-overrides`
(admin defaults) and
`/api/experimental/organizations/{organization}/members/{user}/chats/model-overrides`
(personal overrides); the legacy deployment-level routes are removed.
chatd resolves overrides via the chat's organization, restoring the
hard-failure contract for configured-but-unusable title generation
overrides. The deployment-level `AllowUsers` switch and advisor runtime
limits stay deployment-scoped.

The Coder Agents settings UI gains a per-organization "Defaults &
overrides" page under AI Settings > Models, and the personal overrides
page gains an organization selector for users in multiple organizations.
Advisor telemetry now reports per-organization override rows.

**BREAKING CHANGE**: Existing deployment-level overrides are dropped,
not migrated. Every organization starts with no overrides after upgrade,
and model selections must be re-applied in the new settings. The legacy
deployment-level override endpoints are removed.

Closes https://linear.app/coder/issue/CODAGT-872

Ethan 3809314b31 refactor!: consolidate chat model availability (#28440)
## Summary

Consolidate chat model management and runtime availability into a single
organization model collection contract. The organization model response
now includes provider availability, unavailable reasons, and
unsupported-provider details, so callers no longer need a separate
availability request.

Depends on #28439.

## Problem

The organization-scoped API exposes two overlapping representations of
the same chat models:

```text
GET /api/experimental/organizations/{organization}/chats/models
GET /api/experimental/organizations/{organization}/chats/models/available
```

The collection route returns organization-owned model configurations and
redacted provider descriptors. The availability route returns a second
catalog-oriented response with provider availability and synthetic
catalog entries. Callers must fetch, reconcile, and cache both responses
even though they describe the same effective set of models.

This creates duplicated server logic and separate SDK, OpenAPI, and
frontend types. It can also produce inconsistent client state when one
request succeeds while the other fails or when the two responses are
refreshed at different times.

## Fix

Return all model-management and runtime-availability information from
the organization model collection route:

```text
GET /api/experimental/organizations/{organization}/chats/models
```

`OrganizationChatModelsResponse` continues to return the caller-readable
organization model configurations and redacted provider descriptors.
Provider descriptors now also include:

- `available`
- `unavailable_reason`

The response additionally includes `unsupported_providers`, allowing
clients to explain configurations that the Agents harness cannot use.

Frontend model settings, agent creation, existing chat recovery, and
model override surfaces now consume this single collection query. This
keeps model ownership, caller visibility, provider availability, and
unsupported-provider guidance in one cache entry and one authorization
path.

The default-organization compatibility route remains available:

```text
GET /api/experimental/chats/models
```

It now returns the same consolidated `OrganizationChatModelsResponse`
contract instead of the former availability response.

## Breaking change

This removes the separate organization model availability endpoint:

```text
GET /api/experimental/organizations/{organization}/chats/models/available
```

Clients using that endpoint must migrate to:

```text
GET /api/experimental/organizations/{organization}/chats/models
```

This PR also removes the corresponding public experimental client and
schema surface:

- `ExperimentalClient.ChatModelAvailability`
- `ChatModelAvailabilityResponse`
- `ChatModelProvider`
- `ChatModelCatalogEntry`
- The generated OpenAPI schema and frontend API/query types for the
availability endpoint

Callers must use `ExperimentalClient.ChatModels` and
`OrganizationChatModelsResponse` instead. Availability is now reported
on each `ChatModelProviderDescriptor`, and unsupported providers are
returned in `OrganizationChatModelsResponse.UnsupportedProviders`.

The default-organization compatibility route retains its URL, but its
response schema changes from `ChatModelAvailabilityResponse` to
`OrganizationChatModelsResponse`. Direct HTTP clients and generated
clients that decode the previous response type must be updated even if
they do not use the removed organization-scoped `/available` route.

Ethan aefc761fcf feat!: enforce organization scope for chat models (#27959)
## Summary

Move chat model management and runtime availability to
organization-scoped API routes. The API now identifies the organization
in every model-management operation, applies chat model RBAC and ACLs
within that organization, and returns only models the caller can use
there.

Depends on #27958.

## Problem

Chat model configurations now belong to organizations, but the existing
experimental management and discovery APIs are deployment-shaped. Their
routes do not identify an organization, SDK methods do not accept an
organization ID, and item operations address a model configuration by ID
alone.

That contract cannot safely expose organization-owned model
configurations. It also does not provide the organization-specific
provider information, authorization behavior, ACL management, or
recovery guidance needed by the settings and chat clients later in the
stack.

## Fix

Add organization-scoped chat model endpoints under:

```text
/api/experimental/organizations/{organization}/chats/models
```

The new API provides:

- Organization-scoped model listing and creation.
- Model get, update, and delete operations scoped by both organization
and model ID.
- Model ACL read and update operations.
- Organization-scoped runtime availability and provider status.
- Redacted provider descriptors for model-management clients.
- Chat model RBAC and row ACL enforcement for writes, runtime discovery,
and Chatd model selection.
- Recovery guidance when a chat's organization has no usable local
model.

Historical chats can retain a model reference owned by another
organization, but runtime selection uses an authorized local default
when one is available. Foreign, inaccessible, disabled, and otherwise
unusable models are not exposed as usable selections for the
organization.

The existing collection and availability routes remain as
default-organization compatibility endpoints in this layer:

```text
GET  /api/experimental/chats/model-configs
POST /api/experimental/chats/model-configs
GET  /api/experimental/chats/models
```

These compatibility routes do not provide access to models in
non-default organizations. The previous unscoped item update and delete
routes are removed because item operations must include the owning
organization.

## Breaking change

This changes the experimental HTTP API and Go SDK contracts for chat
model management.

Clients must migrate model-management and availability requests to the
organization-scoped routes and provide an organization identifier. In
the Go SDK, the following methods now require an organization ID:

- `ChatModelAvailability`
- `ChatModels`
- `CreateChatModel`
- `UpdateChatModel`
- `DeleteChatModel`

`ChatModels` also changes its return value from `[]ChatModel` to
`OrganizationChatModelsResponse`, which includes the organization models
and the redacted provider descriptors required by management clients.
New item and ACL methods likewise require both the organization ID and
model ID.

The default-organization compatibility routes reduce the immediate
impact for collection and availability callers, but they do not preserve
the previous item API or SDK method signatures. Generated clients and
direct consumers of the experimental API must be updated before adopting
this change.

Ethan f32592ec6b feat!: scope chat model configs to organizations (#27955)
## Summary

Scope chat model configurations and runtime model resolution to
organizations. Each model configuration now belongs to exactly one
organization, each organization can have its own default model, and
Chatd only uses models that belong to the chat's organization.

Depends on #27968.

## Problem

Chat model configurations are currently deployment-wide even though
chats belong to organizations. A default model, explicitly selected
model, or configured model override can therefore reference the same
model configuration from every organization. This prevents model
catalogs and defaults from being isolated by organization and allows a
chat to retain or select a model that its organization does not own.

Existing model configurations also have no organization ownership or
organization-scoped ACL data, and the database enforces a single live
default across the entire deployment.

## Fix

Add required organization ownership and ACL storage to chat model
configurations. The migration assigns every existing configuration to
the default organization, seeds organization-wide read access, and
replaces the deployment-wide default constraint with a per-organization
constraint.

Scope Chatd lookup, admission, fallback, and queue-promotion behavior to
the chat's organization:

- New chats use the usable default model from their organization.
- Explicit model selections from another organization are rejected.
- Deployment or personal overrides that point to a foreign model are not
used for the chat.
- Historical cross-organization model references remain unchanged in the
database, but runtime generation falls back to a usable local default.
- Queue promotion resolves unavailable, disabled, missing, or foreign
stored models to the usable local default and fails when no usable local
default exists.

The existing model configuration management and availability routes
remain compatibility routes for the default organization in this layer.
A later layer in the stack adds organization-scoped management routes
and updates clients to use them.

## Breaking change

This changes chat model behavior from deployment-wide to
organization-scoped. Existing configurations are migrated only to the
default organization; they are not copied into every organization.

As a result:

- A non-default organization no longer inherits the deployment's
existing default model.
- Creating a chat in an organization without a usable local default
fails with `400: No default chat model config is configured.`
- Explicitly selecting a configuration owned by another organization
fails with `400: Model config does not belong to the specified
organization.`
- Existing chats whose stored model belongs to another organization can
generate only if a usable local default is available; otherwise
generation fails.

Deployments using Agents in non-default organizations must configure a
usable default chat model separately for each organization after the
organization-scoped management layers in this stack are available.

Michael Suchacz 9168dbf4d3 refactor(coderd/x/chatd): unify LLM model-call construction behind a resolver (#28145)
Centralizes every LLM client build in chatd behind one resolver and
makes all model calls behave the same, instead of preserving per-flow
quirks.

## Why

`chatd` built LLM clients in five places (standard turn, compaction
override, quickgen, title override, advisor), each repeating config
parsing, route resolution, client construction, and debug wrapping with
slightly different behavior. An earlier iteration of this PR centralized
construction but preserved every historical quirk behind
purpose-specific spec constructors and policy flags. Review concluded
the quirks themselves were the problem.

## What changed

- `Server.resolveModelCall` (`modelcall.go`) is the single pipeline from
a `modelCallSpec` to a ready client plus call metadata. Callers build
spec literals inline; the only spec fields are data: model source (chat
config, explicit config row, or fixed provider/model pair for computer
use), requested reasoning effort, chatd-scoped routing, and build
options.
- Uniform behavior for every call:
- Provider options are always derived. Whole-chat summaries, turn status
labels, and chat-model compaction summaries previously sent none; they
now follow the config like everything else.
- `MaxOutputTokens` always defaults to 32k when the config leaves it
unset. The compaction summary call nulls the cap after copying the
template because it is non-streaming and the Anthropic SDK rejects
non-streaming requests whose cap implies a completion over ten minutes.
- Debug recording always wraps the client when chat debug is enabled,
labeled with the resolved provider/model. The debug-rebuild paths
(`manualTitleDebugSpec`, `quickgenDebugSpec`) are deleted; debug helpers
now only create and finalize run records, since run association flows
through the generate context, not the model.
- Clients are always constructed with the configured model string and
unmutated route, so AI Gateway validation sees the name exactly as
configured. The resolved identity feeds metadata, logs, and debug labels
only.
- `resolvedModelCall.newCall` / `newObjectCall` are the only production
constructors of `fantasy.Call` / `fantasy.ObjectCall`; object calls now
carry the config's sampling parameters.
- Net: -240 lines.

## Validation

- Full `./coderd/x/chatd/...` suite green (PostgreSQL-backed).
- Red-green toggles verified for the three key unifications (option
derivation, token default, summary cap removal).
- ARCHITECTURE.md: prose the refactor made stale is deleted; no new
resolver documentation is added.

Michael Suchacz 8eb1e43f0b feat: apply reasoning effort and surface thinking blocks for Google chat models (#28273)
## Problem

Selecting a reasoning effort on a Google (Gemini) chat model either got
dropped or broke the request outright, and even when the request
succeeded, Gemini chats never showed thinking blocks:

- The native `fantasygoogle` path had no case in `applyReasoningEffort`
at all, so effort was silently ignored. With only `include_thoughts`
configured, Gemini 3+ models default to no thinking, so chats produced
zero reasoning tokens.
- The path chat generation actually uses today routes Google providers
through aibridge as openai-compat clients and forwarded the raw effort
string as `reasoning_effort`. Google's OpenAI-compatible endpoint
validates that value against the model's supported thinking levels
instead of clamping, so out-of-range efforts fail the whole request with
HTTP 400. Verified against the live Gemini API: `gemini-3.1-pro-preview`
accepts low/medium/high and rejects none/minimal/xhigh/max. Because the
config's default effort is sent whenever the user selects nothing, a
config whose default falls outside the model's supported set failed
every no-selection message.
- Google's OpenAI-compatible endpoint never emits thought text for
`reasoning_effort` requests. Thoughts require
`extra_body.google.thinking_config` with `include_thoughts`, which is
mutually exclusive with `reasoning_effort`, and even then the thought
deltas come back inline in `content` (marked
`extra_content.google.thought`, wrapped in `<thought>` markers) rather
than in the `reasoning_content` field OpenAI-compatible clients parse.
So no reasoning parts were ever produced, persisted, or rendered for
Gemini chats (verified live in UAT).

## Fix

Reasoning effort:

- Map the global reasoning effort scale onto Google's `thinking_level`
in `applyReasoningEffort`, gated to Gemini 3+ models and clamped to each
model's supported subset (3.0 Pro launched with LOW/HIGH only, 3.1 Pro
added MEDIUM, Flash accepts all four through 3.6 while 3.7 and the
latest flash aliases drop MINIMAL, image models accept HIGH plus MINIMAL
for flash). Pre-Gemini-3 models reject `thinking_level`, so effort
degrades to a no-op for them and a config-pinned level is dropped at
call time instead of failing every generation.
- Add `thinking_level` to `ChatModelGoogleThinkingConfig` so admins can
pin a level for configs without user-selectable effort. A resolved
per-turn effort overrides the pinned level; an explicit
`thinking_budget` wins over both since the Google API rejects requests
that set `thinking_budget` and `thinking_level` together, and config
validation now rejects that combination up front. The admin panel picks
up the new field automatically through the generated model-options
schema.

Thinking blocks on the openai-compat path (the path chat generation
uses), translated in both directions at the existing Gemini transport
seam:

- chatd's OpenAI-compat request patch swaps `reasoning_effort` for an
equivalent `extra_body.google.thinking_config` with `include_thoughts`
enabled: `thinking_level` on Gemini 3+ (clamped to the model's supported
subset), `thinking_budget` on earlier models (effort `none` maps to
budget 0, which disables thinking). Non-Gemini models and non-Google
routes are untouched.
- The same transport rewrites Google's responses so thought output
surfaces as `reasoning_content`, which fantasy already converts into
reasoning parts: streaming bodies are rewritten per SSE line (preserving
streaming latency), JSON bodies in place, with the
`<thought>`/`</thought>` markers stripped at the transitions.
- aibridge's chat-completions interception preserves the `extra_body`
passthrough that openai-go's typed params silently drop, forwarding it
to Google upstreams only, so the chatd -> aibridge -> Google route
carries the thinking config end to end.

## Validation

- `go test ./coderd/x/chatd/... ./aibridge/... ./internal/googleopenai
./codersdk` pass; golangci-lint clean on touched packages.
- New unit tests cover the effort-to-level mapping for every effort
value, per-model clamping on both paths, the effort-to-thinking_config
request swap (level, budget, pinned-config precedence, non-Gemini
passthrough), SSE and JSON thought-response rewriting (fixtures mirror
live captures, including tool-call and no-thought streams), an
end-to-end fake-SSE test through the fantasy pipeline proving reasoning
deltas emerge with markers stripped, and aibridge `extra_body`
preservation (including proof the typed round trip drops it).
- Verified live against `generativelanguage.googleapis.com` on
`gemini-3-flash-preview` and `gemini-2.5-flash` through the real
chatprovider stack: reasoning deltas stream through with markers
stripped and answer text intact.
- Live UAT on a dogfood deployment (remote Coder Agents chat, 4 rounds):
effort clamping verified end to end (rounds 1-2), the missing-thoughts
limitation isolated (round 3), and the fix validated (round 4):
expandable, readable thinking blocks render for
`gemini-3.1-pro-preview`, `gemini-3-flash-preview`, and
`gemini-2.5-flash` at effort=high; no `<thought>` marker leaks;
effort=none produces no block and no 400; multi-turn history replay
works with a thinking block on each turn.
- `make gen` regenerated `typesGenerated.ts` and
`chatModelOptionsGenerated.json`; `pnpm -C site lint:types` passes.

Danielle Maywood 5480299cef fix: serialize empty MCP tool properties as {} not null for OpenAI (#28380)
## Summary

Fixed a bug where MCP tools with an empty `properties` schema had their
tool definitions sent to OpenAI with `"properties": null`, causing
OpenAI to reject the request.

## Problem

When an MCP server reports a tool with an empty input schema, e.g.:

```json
{
  "type": "object",
  "properties": {},
  "required": []
}
```

Coder was forwarding the tool definition to OpenAI as:

```json
{
  "type": "object",
  "properties": null
}
```

OpenAI's function-calling API rejects `properties: null`, making these
tools unusable with OpenAI models.

## Root cause

The empty `properties` object collapsed to Go `nil` at two layers:

1. `agent/x/agentmcp/manager.go` `toolInputSchemaMap` stripped the
present-but-empty `"properties": {}` (guarded by `len(properties) > 0`),
so the wire copy lost it entirely.
2. `coderd/x/chatd/chatloop/chatloop.go` `buildToolDefinitions` embedded
`info.Parameters` directly into the input schema. When nil,
`encoding/json` marshals it as `null`.

## Fix

- `buildToolDefinitions` now substitutes an empty object when
`Parameters` is nil, mirroring the existing `required` guard (the sink,
protects all tool sources).
- `toolInputSchemaMap` now preserves an empty `properties` object
instead of dropping it (the upstream producer).

## Tests

Added regression tests (failing before, passing after) covering both
layers and asserting the schema serializes to
`{"type":"object","properties":{}}`:

- `TestBuildToolDefinitionsNilPropertiesBecomesEmptyObject`
- `TestToolInputSchemaMapPreservesEmptyProperties`
-
`TestWorkspaceMCPToolInfosFromResources/EmptyPropertiesYieldsEmptySchema`

Michael Suchacz a3eb1ee930 fix: gate MCP user tokens on owner-scoped personal RBAC (#27945)
Re-gates every `mcp_server_user_tokens` dbauthz method from
`rbac.ResourceDeploymentConfig` onto owner-scoped personal actions,
mirroring the `external_auth_links` prior art. These are per-user
credential rows, not deployment config, and the old gate forced every
call site to elevate with `dbauthz.AsSystemRestricted`.

## Summary

- Reads gate on `ActionReadPersonal` and writes on
`ActionUpdatePersonal` against the token owner
(`MCPServerUserToken.RBACObject()` derives from `user_id`). The id-keyed
refresh and refresh-failure mutations resolve the owner via a
`GetMCPServerUserTokenByID` prefetch inside dbauthz; the mutation
queries cannot retarget a row's owner, so there is no fetch-authorize
race.
- All seven token-path `AsSystemRestricted` elevations in
`coderd/mcp.go` and all four in chatd are removed along with their
`//nolint:gocritic` markers; handlers use the request actor.
- The daemon-wide chatd subject keeps only `ActionReadPersonal` on
`ResourceUser`. Background token refresh and failure persistence use a
new per-user `AsChatdTokenOwner` subject holding only user-level
`ActionUpdatePersonal` scoped to the token owner (both mutations resolve
the row via the underlying store, so the subject needs no read grant),
and chatd never holds site-wide personal-write access. `TestAsChatd`
pins the complete `ResourceUser` action set and
`TestMCPServerUserTokensAuth` exercises both subjects against the real
authorizer.
- New strict-authorizer test (`rbac.NewAuthorizer` against real rows):
owner passes get/upsert/delete, a stranger fails, and an org admin of
another org fails.

No user-visible behavior change. Stacked on #27944. Completes the MCP
org-separation stack.

Michael Suchacz 7ca7c30f40 feat: add group and user ACLs to MCP server configs (#27944)
Adds group and user ACLs to org-scoped MCP server configs so
organizations can restrict specific MCP servers to subsets of members,
mirroring the template ACL pattern.

## Summary

- Migration adds `group_acl`/`user_acl` JSONB columns (nested `{"<id>":
{"permissions": [...]}}` shape) and seeds every existing config with its
organization's Everyone group read entry (the Everyone group ID equals
the org ID), so member access is unchanged by default. Creation seeds
the same entry.
- The blanket org-member read grant from the base PR is replaced by ACL
evaluation: Rego requires org membership for every ACL grant, and
`GetAuthorizedMCPServerConfigs` compiles ACL-aware SQL filters.
- New `ActionShare` (org admins) gates `GET|PATCH
/api/experimental/organizations/{organization}/mcp-servers/{mcpserverconfig}/acl`
(nested under the organization like the rest of the config surface).
PATCH validates principals against the config's organization, merges
sparse updates under a row lock, stamps `updated_by`/`updated_at`, and
is audited as a Write with `Old` captured before authorization. A config
deleted concurrently between the middleware fetch and the locked
re-fetch is concealed as 404, matching the update and delete handlers.
ACL columns are tracked in the audit table.
- ACL management is available in all editions (no enterprise
entitlement), documented in the MCP servers page. Revoking an ACL does
not retro-strip already-selected configs from existing chats; new
selection is blocked at chat create.
- Force On respects the ACL: the forced set is loaded as the chat owner,
so a `force_on` server whose ACL denies the owner never attaches at
create, send, or generation time.
- No rolling-upgrade machinery: upgrades run in scheduled maintenance
downtime, so the migration only backfills existing rows; the API sets
the Everyone read grant explicitly on every insert.

Stacked on #27943. Part of the MCP org-separation stack.

Closes https://linear.app/codercom/issue/CODAGT-712

Michael SuchaczandMathias Fredriksson 443e3b9b80 feat!: org-scope MCP server configs with RBAC (#27942)
Moves `mcp_server_configs` from deployment scope to organization scope
so each organization fully controls the MCP servers its members can use
with Coder Agents.

## Summary

- Migration: adds `organization_id` (NOT NULL, FK) and keeps existing
rows as the default organization's originals with credentials intact.
Other organizations start with no MCP servers and configure their own;
nothing is copied across organizations. Chats outside the default
organization keep any now-cross-organization `mcp_server_ids` entries;
the runtime already ignores IDs that do not resolve in the chat's
organization, so no data rewrite is needed. Slug uniqueness becomes
`(organization_id, slug)`.
- RBAC: new org-scoped `ResourceMCPServerConfig` with regosql converter
and `GetAuthorizedMCPServerConfigs`; org admins get in-org CRUD, org
members get read (replaced by ACL evaluation in the follow-up ACL PR in
this stack).
- API: all config routes nest under the organization, matching
templates: `POST|GET
/api/experimental/organizations/{organization}/mcp-servers` and
`GET|PATCH|DELETE .../mcp-servers/{mcpserverconfig}` (plus
`oauth2/connect`), resolved by a read-only param middleware that
conceals read-denied and cross-organization access as 404. Two routes
stay on the frozen `/api/experimental/mcp/servers/{mcpServer}` block:
the OAuth2 callback (the redirect URI baked into existing AS-side client
registrations) and `oauth2/disconnect`, which must remain reachable by
users removed from the organization so they can still revoke their token
grant.
- Chat runtime: selection validation and generation resolve configs
strictly by IDs, enabled state, and the chat's organization in SQL;
requested duplicates are normalized; invalid or cross-org IDs are
rejected with the precise ID list. IDs already persisted on a chat are
exempt from message-time rejection so disabling a selected server never
blocks sends; generation skips servers that are no longer usable.
- Frontend: API layer and admin settings pages target the new endpoints.
The admin page manages the default organization's servers; the org
picker is tracked separately (CODAGT-714).

- Security hardening from review: OAuth user grants are additionally
bound to `oauth2_revocation_url` (changing it invalidates grants, and a
racing OAuth callback gets 409 instead of recreating a grant).
Stack-wide SSRF protection for MCP config-directed traffic was split
into its own PR at the top of this stack (#28242) to keep this diff
reviewable; this PR keeps main's existing discovery IP-range guard.
OAuth2 auto-discovery now completes before the config row is inserted: a
failed discovery persists nothing, and there is no provisional row that
concurrent updates could race against.

Two follow-up PRs in this stack were split out to keep this diff
reviewable: #28064 completes the swagger annotations for the moved
routes (main already ships these experimental MCP handlers unannotated),
and #28065 carries hardening fixes and regression pins on top of the
cutover.

- Force On enforcement (landed on main mid-review) is org-scoped: the
forced set is read per chat organization
(`GetForcedMCPServerConfigsByOrganization`), so another organization's
`force_on` server never attaches to a chat.

## Breaking changes (experimental API)

The MCP server config endpoints move from the deployment-scoped
`/api/experimental/mcp/servers` block to organization-nested paths:
`POST|GET /api/experimental/organizations/{organization}/mcp-servers`
and `GET|PATCH|DELETE
/api/experimental/organizations/{organization}/mcp-servers/{mcpserverconfig}`
(plus `oauth2/connect`). The old paths are removed, so API consumers
must supply an organization. Two routes intentionally stay on the frozen
`/api/experimental/mcp/servers/{mcpServer}` block: the OAuth2 callback
(its redirect URI is baked into existing AS-side client registrations)
and `oauth2/disconnect` (must remain reachable by users removed from the
organization). These endpoints are under `/api/experimental`, so no
deprecation window is provided.

## Rolling upgrades

During a rolling deploy, an old replica creating an MCP config can fail
the new `NOT NULL organization_id` constraint until it is upgraded
(reads are unaffected: old binaries' generated queries select their own
column lists). This matches the repo's existing precedent for additive
NOT NULL migrations (000562) and affects only the admin config-create
path in the upgrade window.

Upgrades are expected to run in scheduled maintenance downtime with the
database locked during migration, so the migration ships no
rolling-upgrade compatibility machinery. The down migration deletes
organization-created configs (their chat references are cleaned by the
000510 delete trigger) and restores deployment-wide slug uniqueness.

Part of the MCP org-separation stack (CODAGT-711 -> CODAGT-717 audit ->
CODAGT-712 ACLs -> CODAGT-806 token RBAC).

Closes https://linear.app/codercom/issue/CODAGT-711

UAT: validated end to end on a two-org dogfood deployment, including a

revised to keep existing rows in the default organization only (no
per-organization copies); that revision is covered by the migration test
suite.

Ben Potter 8a7e8d9d5b refactor: move chat prompt sanitization into codersdk (#28283)
Exports `SanitizePromptText` (and its helpers) from `codersdk` instead
of `coderd/x/chatd`, so API consumers can sanitize prompt text exactly
the way the server stores it.

## Why

coder/terraform-provider-coderd#412 adds a `coderd_chat_system_prompt`
resource whose `system_prompt` attribute compares values by their
sanitized forms (otherwise the trailing newline from
`file("system-prompt.md")` is perpetual drift, since the server stores
the sanitized value). That currently requires a mirrored copy of the
sanitizer in the provider, which can silently rot. Per review there
([discussion](https://github.com/coder/terraform-provider-coderd/pull/412#discussion_r3801110795)),
the sanitizer should be exported from `codersdk` and imported instead.

## What

- `coderd/x/chatd/sanitize.go` → `codersdk/promptsanitize.go` (pure
move; package + doc-comment note about why it lives in codersdk)
- `coderd/x/chatd/sanitize_test.go` → `codersdk/promptsanitize_test.go`
- Callsites updated (`exp_chats.go`, `chatd.go`, `subagent.go`,
`context_prompt.go`); no wrapper left behind, single source of truth
- No behavior change

Michael Suchacz 7724ee281a feat: defer MCP tool schemas behind a find_tools search (#28225)
## Summary

When the `mcp-tool-search` experiment is enabled, chatd stops inlining
connected MCP tool schemas into every generation. It instead exposes a
built-in `find_tools` tool whose description carries a compact catalog
of the deferred tools, and only ships full JSON schemas for tools the
model has activated by searching or by calling them directly.

Closes [CODAGT-760](https://linear.app/coder/issue/CODAGT-760).

## Problem

Tool-heavy agent configurations (GitHub, Linear, Notion, and dev-tooling
MCP servers) inline over 100k tokens of tool schema definitions into
every generation. Initial uncached requests reached ~216k tokens with
time-to-first-token close to nine minutes, while the model typically
invokes only a handful of tools per turn.

## How it works

- `decideMCPToolSearch` defers external and workspace `.mcp.json` MCP
tools whenever the experiment is enabled. Native, dynamic, provider,
skill, and transport tools are never deferred.
- `find_tools` embeds a server-grouped catalog in its tool description
(degrading to names-only, then counts-only, then a constant-size summary
past a context-scaled size cap) and scores keyword matches across tool
names, descriptions, parameter schemas, and server metadata. Queries can
scope to one server with a `server:` prefix, and exact `names` arguments
always activate.
- Activation state is ephemeral: it is re-derived each generation from
surviving chat history (`find_tools` results and direct calls to
deferred tools), so activations naturally lapse when compaction
summarizes them away. Aggregate activated schema weight is capped at 10%
of the context window, shedding the least recently activated schemas
first; `find_tools` shares that budget across parallel calls in one
step. No new persistence.
- Deferred tools stay registered for execution, so the model can call a
cataloged tool directly without searching first; the schema is activated
for subsequent steps.
- Fail-open: the experiment being disabled, an empty candidate set, or
an MCP tool named `find_tools` all disable deferral, leaving today's
behavior byte-identical on the wire.
- Prometheus counters/histograms track `find_tools` calls, matches,
activations, and deferred token weight.
- The conversation timeline renders `find_tools` calls with a collapsed
search summary and expandable match list, falling back to the generic
renderer on malformed payloads.

## Validation

- Unit tests for the catalog, matcher, experiment-gated decision, and
activation derivation; end-to-end chatd generation tests covering
search-then-call, direct-call activation, experiment-off wire parity,
compaction lapse, and subagent tool gating.
- Storybook interaction tests for the timeline rendering and
malformed-payload fallback.
- Remote dogfood UAT on dev.coder.com passed: deferral with a real MCP
server and Anthropic model, direct calls without prior search,
activation persistence across turns, experiment-off parity, and clean
UI/console.

Michael Suchacz 119f2b1dd9 feat: limit concurrent chat agents with pooled admission (#27902)
Limits concurrent chat generation on capped deployments to 5 root chats
and 10 delegated subagent chats. The pools are deployment-wide and
independent, so delegated work can continue while root capacity is full.

The default caps live in AGPL code. Enterprise contributes only a
licensing unlock, so unlicensed deployments stay capped and cannot fail
open. Licensed deployments are uncapped while Agent Hours usage stays
below an explicit hard limit. Deployments without a hard limit remain
uncapped, and reaching the Agent Hours allocation only triggers
warnings.

Admission happens before a worker takes chat ownership. Capped
deployments serialize admission across replicas with a
transaction-scoped advisory lock and derive active and queued state from
current ownership plus fresh runner heartbeats, rather than persisted
queue markers or per-replica state. The acquisition query returns a
bounded, pool-interleaved candidate set instead of ranking the whole
backlog; a migration replaces the acquisition index with a pool-aware
one. Refused chats stay running but unowned, and interrupt requests
bypass admission so users can stop queued or over-cap chats.

The single-chat API derives `queued_for_capacity` from live pool state;
list endpoints do not report it. The UI polls that value every 5 seconds
while a chat is running and shows a callout when the chat is waiting for
capacity.

Updates the administrator documentation and deployment-wide Prometheus
gauges for active and queued agents. Replica-level values must be
aggregated with `max`, not `sum`.

Michael Suchacz 93c6faf1de fix(coderd): send assigned chat model IDs verbatim (#28144)
Fixes #27361 (CODAGT-832).

## Problem

When an Agents model was configured under a non-gateway provider type
(e.g. Anthropic or OpenAI) with a model ID whose first `/`- or
`:`-segment matched a built-in provider name (`anthropic`, `azure`,
`bedrock`, `google`, `openai`, `openai-compat`, `openrouter`, `vercel`),
`chatprovider.ResolveModelWithProviderHint` parsed it as a canonical
`provider/model` reference: the prefix was stripped and the request
rerouted to the embedded provider type, overriding the provider the
admin explicitly assigned. LLM gateways (e.g. LiteLLM) that namespace
their catalogs as `bedrock/...` or `anthropic/...` behind an Anthropic-
or OpenAI-type provider failed with an opaque upstream "Model not
found", and escaping was impossible (`bedrock/bedrock/...` still
rerouted).

## Fix

A valid provider hint is now authoritative:
`ResolveModelWithProviderHint` returns the assigned provider and the
verbatim model ID whenever a hint is present. Canonical `provider/model`
and `provider:model` parsing applies only to hint-less resolution paths.
Every production call site derives the hint from the model config's
explicitly assigned AI provider, so the assignment always wins.

The save-time guard rejecting slash-namespaced models on OpenRouter-like
providers typed as `openai` (provider named `openrouter` or hosted at
`openrouter.ai`) is kept: that combination remains a misconfiguration
whose correct fix is the `openrouter` provider type, and rejecting it
early beats a confusing upstream error. Its wording no longer claims
prefix stripping happens.

## Back-compat note

A pre-existing config that relied on stripping (e.g. model
`anthropic/claude-x` assigned to an Anthropic-type provider pointing at
the real Anthropic API) now sends the prefixed ID verbatim and will get
a clear upstream model-not-found error; the admin fixes it by editing
the model ID. Nothing in the product ever suggested the canonical form
for assigned models.

## Validation

- Unit: `TestResolveModelWithProviderHint` updated (hints preserve
`bedrock/...`, `anthropic/...`, `provider:...` verbatim; hint-less
canonical parsing unchanged), red-green verified against the old
ordering. Gateway and openai-type provider routing tests assert verbatim
pass-through end to end.
- Full `./coderd/x/chatd/...` suites plus `TestCreateChatModelConfig`,
`TestUpdateChatModelConfig`, and
`TestValidateChatModelConfigProviderModel` pass.
- Remote dogfood UAT on real models (PASS): an openai-type provider
pointed at a Vercel AI Gateway mount returned a real completion for
`anthropic/claude-haiku-4.5`, with trace logs confirming
`provider=openai model=anthropic/claude-haiku-4.5` (verbatim, not
rerouted); gateway-type (`openai-compat`) routing with
`deepseek/deepseek-v4-pro-0813` and the model catalog/picker regressions
pass.

Michael Suchacz 48e1e28638 fix(coderd/x/chatd/chattool): make edit_files schema and errors actionable for models (#28121)
## Problem

Chat `45b87e40-ffe7-49e5-8932-5fd0bdb9e542` on dev.coder.com failed 57
of 75 `edit_files` tool calls. Every failure was the same: the model
omitted `files[].path` (it batched edits per file but only filled in
`edits`), and the error relayed back to the model was:

```
POST http://[fd7a:115c:...]:4/api/v0/edit-files: unexpected status code 400: "path" is required
```

The model retried the identical malformed call dozens of times. Two gaps
made this sticky:

1. The `edit_files` input schema had no field descriptions, so `path`
was only a bare required property.
2. The agent API error reached the model wrapped in HTTP transport noise
(method, internal tailnet URL, status code) with no indication of which
`files` entry was broken.

## Changes

- Add `description` tags to every `edit_files` schema field and state
the path requirement in the tool description.
- Validate `files` entries in the tool before plan-turn checks and the
workspace connection lookup, returning entry-indexed errors such as
`files[1].path is required; provide the absolute path of the file to
edit; no files in this batch were applied`.
- Relay agent API failures with `Message`, `Helper`, `Detail`, and
`Validations` from `codersdk.Error` instead of the raw
transport-prefixed string.

## Validation

- `go test ./coderd/x/chatd/chattool` passes; new tests cover the schema
description, entry-indexed validation errors, and transport-noise
stripping (each verified red-green by toggling the fix off).
- `go build ./...`, `go vet`, and pre-commit (fmt + lint) pass.

Michael Suchacz e92fd8e96f chore: retire mark3labs/mcp-go dependency (#28061)
## Stack Context

PR 6 of 6 in a stack that migrates every Coder MCP surface from the
archived `github.com/mark3labs/mcp-go` library to the official
`github.com/modelcontextprotocol/go-sdk` v1.7.0.

Stack: #28056 -> #28057 -> #28058 -> #28059 -> #28060 -> #28061

## Why

With every production surface migrated, this PR removes the mark3labs
dependency entirely and converts the remaining test fixtures.

- Migrates the remaining mark3labs test fixtures (coderd MCP e2e tests,
chatd fixtures, mcpclient fixtures, and the Force On MCP policy tests)
to official stateless SDK servers.
- Removes `github.com/mark3labs/mcp-go` from `go.mod` and drops the
corresponding dependabot ignore entry. Zero references remain repo-wide.
- Updates the MCP docs for the 2026-07-28 protocol: stateless Streamable
HTTP behavior, the supported 2024-11-05 through 2026-07-28 protocol
range, and explicit non-features (resources, prompts, structured output,
elicitation, MCP Tasks).
- The e2e ping assertion is removed because MCP 2026-07-28 removed the
ping method.

Michael Suchacz 1e546ea8a3 feat(coderd/x/chatd/mcpclient): migrate external MCP client to official Go SDK (#28058)
## Stack Context

PR 3 of 6 in a stack that migrates every Coder MCP surface from the
archived `github.com/mark3labs/mcp-go` library to the official
`github.com/modelcontextprotocol/go-sdk` v1.7.0.

Stack: #28056 -> #28057 -> #28058 -> #28059 -> #28060 -> #28061

## Why

The chatd external MCP client (admin-configured MCP servers used by
Agent chat) now holds `*mcp.ClientSession` connections created via
`mcp.NewClient` and `Client.Connect`, with `StreamableClientTransport`
or `SSEClientTransport` per server config.

- Auth and identity headers are injected through a custom
`http.RoundTripper` because the official SDK has no per-header transport
options.
- Tool input schemas are extracted from the SDK's `map[string]any`
decoding.
- Content conversion handles the official pointer content types; the SDK
decodes blob resources into raw bytes, so binary content is handled
without an extra base64 round trip.
- Test fixtures are official stateless Streamable HTTP servers.

Cian JohnstonandCopilot Autofix powered by AI 3f9e8cca2a chore: add test coverage for chatd compaction (#28053)
## Summary

Adds test coverage for the three compaction-decision functions in chatd
that had zero tests: `latestPromptUsage`, `shouldCompactPromptUsage`,
and `contextTokensFromUsage`.

AIGOV-585 hypothesized that chatd's token counting logic was incorrect —
that it compared a cumulative sum of prompt tokens across all
agentic-loop steps against the context window. The tests disprove this:
`latestPromptUsage` returns the last persisted assistant message's
usage, not a sum. The actual bug was in the aibridge streaming
interceptor, which summed usage across SSE chunks and persisted inflated
values (fixed in `ad100452d4`).

## What's tested

- `TestLatestPromptUsage` — pins that the compaction path reads the last
step's usage (5,400), not a cumulative sum across steps (15,600). If
someone wires `TotalUsage` into the compaction path as the issue
suggested, this fails.
- `TestShouldCompactPromptUsage` — covers the threshold decision with
the inflated value from the issue (417,012 → compacts), the correct
value (6,000 → doesn't compact), cache token counting, and both disable
guards (threshold=100, contextLimit=0).

<details>
<summary>Plan / investigation notes</summary>

- Traced the full flow: `chatloop.go:993` sets `result.usage =
part.Usage` from the per-step `StreamPartTypeFinish` event, not the
accumulated `TotalUsage` from `agent.go:544`. chatd never calls
fantasy's `Agent` interface.
- The `TotalUsage` accumulation in `agent.go:544` is only used for cost
attribution, not context occupancy.
- Commit `ad100452d4` fixed the real bug in
`aibridge/intercept/chatcompletions/streaming.go` (cross-chunk usage
summation for vLLM-style backends).
- Tests reuse existing `dbMessage` and `withUsage` helpers from
`message_conversion_test.go` (same package).

Michael Suchacz 1458d27d78 fix: allow manual chat compaction from the error state (#28022)
A chat that fails generation with a context overflow (for example `Input
length 262625 exceeds the maximum allowed input length of 262112
tokens`) is stuck in a catch-22: `POST /chats/{id}/compact` returns 409
because the `RequestCompaction` transition is only allowed from the
waiting state, and the only other way out of the error state is sending
or editing a message, which re-runs generation with the same oversized
prompt and fails again. Compaction is exactly the recovery a
context-overflowed chat needs, and it is unreachable exactly when it is
needed.

Three semantic changes:

- Allow `RequestCompaction` from the error states: `E0 -> R0` and `E1 ->
R1` (queued messages are preserved and processed after the compaction
turn).
- Clear `last_error` in `Tx.RequestCompaction`, matching the
architecture rule that transitions leaving `E0`/`E1` clear the stored
error. Without this a successful compaction would land in waiting with a
stale persisted error.
- Grant the compaction turn a fresh history epoch: a
`grant_history_epoch` flag on `UpdateChatExecutionState` sets
`history_version = snapshot_version`, resets `generation_attempt`, and
clears `retry_state` in the same atomic update that clears `last_error`
(mirroring the `chat_messages` trigger postcondition). The transition
inserts no history, so without this the turn inherits the failed turn's
spent retry budget, and resetting the counter alone could collide with
message part episode keys still retained on the erroring replica.

No frontend change is required: the chat input is already enabled in the
error state and `/compact` submission already handles both the success
and 409 paths. Also updates ARCHITECTURE.md (transition matrix,
endpoint, and manual compaction sections), the endpoint's swagger
description, and SDK comments.

Michael Suchacz bde38e9d10 fix(coderd/x/chatd): synchronize aibridgeTestFactory recorded fields (#28031)
Fixes the data race in the chatd test helper `aibridgeTestFactory`
reported in CODAGT-917 (`test-go-race-pg` flake in
`TestAwaitSubagentCompletion/Timeout`).

`TransportFor` recorded `providerName` and `source` with plain field
writes. Tests that start the chat worker share one factory between
concurrently running chat runners (parent chat and spawned subagent), so
two runners resolving models at the same time raced on those writes.

The fix guards the recorded fields with a mutex and reads them through a
locked `recorded()` accessor at the three asserting call sites.

Verified with a red-green repro: concurrent `TransportFor` calls on one
factory failed `go test -race` with the exact CI signature (lines 37-38)
before the fix and pass after it. Also ran `go test -race
./coderd/x/chatd -run TestAwaitSubagentCompletion -count=10` and the
full `go test -race ./coderd/x/chatd` package, both clean.

Audited every other `aibridge.TransportFactory` implementation and
`aibridgeTestFactory` use site for the same defect:
`chattest.MockAIBridgeTransport` is already mutex-guarded,
`stubTransportFactory` (coderd/aibridge_test.go) records via a channel,
`providerRoutedTransportFactory` (chatd_test.go) is a stateless lookup,
and the production factories keep no recorded state. No other occurrence
exists.

Closes CODAGT-917.

Michael Suchacz 57f38b5c24 fix: keep chat attachments while a linking chat exists
Fixes https://linear.app/codercom/issue/CODAGT-616/keep-chat-attachments-while-chats-remain-unarchived

Chat attachments could disappear even though the chat was still available. This happened when a message was saved without recording which attachments it used, or when cleanup deleted attachments before an archived chat itself was removed.

Creating a chat, sending or queuing a message, and editing a message now record both the message and which attachments it uses as one operation. If the chat is already at the 50-attachment limit, the chat change fails without being partially saved.

Concurrent attachment writes serialize the 50-file cap per chat. Cleanup locks candidates and checks again for new links before deleting. If a file becomes unavailable after input validation, create, send, and edit return a clear client error and roll back the chat change.

An attachment stays available while any chat that uses it still exists. After an archived chat reaches the end of its retention period and is deleted, an old attachment that no remaining chat uses can be cleaned up. The retention guide and unavailable-attachment UI text document this lifecycle. This change cannot restore attachments that were already deleted.

The database migration adds two indexes so attachment cleanup stays fast as attachments accumulate.

Michael Suchacz 2e5353bde7 feat: add built-in Browser tab for agent-browser (#27910)
Adds a built-in Browser tab to the Agents page right panel, alongside
the built-in Terminal and Desktop tabs, when the chat's bound agent has
an app with the well-known slug `agent-browser`. The tab shows only
while the app is embeddable and its health is `healthy` (or `disabled`,
for templates without a healthcheck), so it appears and disappears live
as the daemon comes up or goes down. The iframe stays mounted across tab
switches to preserve session state.

To avoid duplicates, the generic Add Tab menu and persisted
workspace-app tabs now exclude the `agent-browser` app. Detection uses
the existing `coder_app` slug and healthcheck signals already present in
the workspace data model. The workspace watch handler compares the agent
app fields the chat UI consumes, so health transitions propagate without
re-render churn on every heartbeat.

On the backend, the chat `execute` tool now exports
`AGENT_BROWSER_SESSION=<chat id>` on every process it starts.
agent-browser resolves its default session from that variable, so
browser automation from each chat lands in its own isolated session
(named by the chat id in the embedded dashboard) instead of a shared
default browser.

Michael Suchacz c97f4da3ac chore: sync fantasy fork with upstream v0.40.0 and openai-go with v3.50.0 (#27981)
Our fantasy fork had drifted far behind upstream charmbracelet/fantasy
(base v0.31.0 vs current v0.40.0). This PR updates the pinned forks
after reconciling which fork hacks upstream has fixed and which we still
need, and adapts this repo to the new APIs.

## Fork updates

- `charm.land/fantasy` ->
[coder/fantasy#51](https://github.com/coder/fantasy/pull/51) (merged):
`coder_2_33` synced with upstream v0.40.0, pinned at the merge commit
`bb10946892ef`.
- `github.com/openai/openai-go/v3` ->
[coder/openai-go#10](https://github.com/coder/openai-go/pull/10)
(merged): `coder/pinned` rebased from v3.16.0 onto upstream v3.50.0
(required by upstream fantasy), pinned at the merge commit
`92b5addb22d2`.
- `coder/anthropic-sdk-go` pin unchanged; the fantasy fork now tracks
the same revision this repo ships.

## Hack reconciliation summary

Dropped from our fantasy diff (upstream now has equivalents, often
stricter): truncated-stream fail-closed detection, Anthropic EffortXHigh
/ computer use / thinking effort / thinking display, replay fidelity for
signed reasoning and web_search errors, PDF and text documents with
sanitized filename titles, refusal finish-reason mapping (upstream also
maps Bedrock `content_filtered`/`guardrail_intervened`), gpt-5.5/5.6
Responses routing, the Go 1.25 downgrade, and the openai-go SSE decoder
and appendCompact patches.

Still fork-only and preserved: OpenAI computer use, OpenAI Responses
replay continuity validation, Anthropic pre-4.6 budget-thinking
conversion plus explicit thinking disable for effort none, Anthropic
RefusalMetadata parsing, Bedrock cross-region inference profile region
mirroring, and openai-go deferred body serialization with the
WithJSONSet fix.

Picked up new upstream features: stream transport retry with in-band SSE
error classification, Bedrock expired-credential refresh, per-message
cache markers for OpenAI-compatible models, tool panic recovery, extra
usage fields in provider metadata, and ClientMetadata on tool results.

## Changes in this repo

- `aibridge/intercept/responses`: `ResponseOutputItemUnion.Arguments`
became a union type in openai-go v3.50; read function-call arguments via
`.OfString` (plus test literal updates).
- `coderd/x/chatd/chatdebug`: register the new fantasy `Call.Headers`,
`ObjectCall.Headers`, and `ToolResultPart.ClientMetadata` fields in the
normalization coverage map (all skipped).
- `aibridge/internal/integrationtest`: make the RST test listener drain
the request before resetting the connection. The new SDK's write path
exposed the previous 1-byte-read race as sporadic `use of closed network
connection` failures; the fix holds over 40 consecutive runs.
- `go.mod`: rewrite the fork provenance comments to describe the
post-sync state.

## Validation

- `go build ./...` and `go vet ./...` clean (vet findings identical to
base).
- Fresh (`-count=1`) runs of `./coderd/x/chatd/...`, `./aibridge/...`,
`./coderd/aibridged/...`, `./coderd/database/db2sdk/`: 37 packages pass.
- `TestClientAndConnectionError` stress-tested 40x clean.
- Both fork PRs have green CI.

Cian Johnston 4e2620d64f fix(coderd/x/chatd): classify bedrock credential errors as non-retryable (#27913)
When a Bedrock provider is misconfigured without authentication methods,
AWS credential resolution fails and AIBridge writes the error as a
plain-text HTTP 500. The fantasy adapter captures the body text in
`ProviderError.ResponseBody`, but `Error()` returns only the SDK
transport wrapper, not the body.

Signal patterns in `chaterror.Classify` checked only `err.Error()` (the
wrapper), missing the useful text in `structured.detail` (the body).
This caused permanent configuration errors to fall through to the
generic 500 rule with `retryable=true`, making the chat worker retry up
to 25 times.

Introduce `combinedText` (merging the wrapper with `structured.detail`)
and widen signal checks that have no dedicated status code to use it:
overloaded, auth, config, usage limit, and timeout patterns. The
deadline signal stays on `err.Error()` to avoid treating ambiguous body
text as a local context deadline. Add a "resolve aws credentials" config
pattern so credential resolution failures classify as config, not
generic.

4b7494be72 feat: harden chat generation runtime instrumentation for billing (#27451)
Closes CODAGT-835

## Summary

`chat_messages.runtime_ms` becomes the billing source of truth for Coder
Agents runtime (summed hourly by #27312), but it was built for
debugging: the June refactor (#26270) silently stopped recording
tool-step runtime, compaction was never measured, and interrupted turns
lost their partial runtime entirely. This PR defines the billable
metric, closes the paths that dropped it, and documents the definition
where the data lives.

## The billable definition

**`runtime_ms` is the wall-clock duration of the model invocation that
produced the persisted message content**, measured from just before the
provider stream opens until it is fully consumed.

What counts:

- Assistant generation steps, in top-level and sub-agent chats
(sub-agents are ordinary chats on the same generation path).
- Compaction summarization calls, persisted on the compaction assistant
message (**new**).
- Interrupted attempts: the message-part episode's lifetime is persisted
on the partial assistant message committed by `FinishInterruption`, so
partial generation time survives interruption (**new**; measured via a
new `Buffer.EpisodeDuration`, which works even though the generation
goroutine and the interrupt task are different tasks).

What deliberately does not count (each is documented in code and docs):

- **Local tool execution.** Tool wall time includes idle waits, most
importantly `wait_agent` polling a sub-agent chat that already bills its
own model invocations; billing the batch would double count, and
excluding one tool from a concurrent batch's wall time is ill-defined.
Pre-refactor instrumentation did include tool time; this makes the
exclusion an explicit product definition instead of a silent regression.
- **Failed model calls whose output is discarded** (retried attempts,
terminal errors, content-filter refusals). They persist no content, so
they bill nothing; billing errs toward undercounting. Notably a
stream-silence timeout can burn 10 idle minutes before a retry, which
should not be billable "active generation". If product later wants
failed attempts billed, that needs a place to persist runtime on error
turns (`FinishError` inserts no rows today) and is a deliberate
follow-up, not instrumentation drift.
- **Ancillary calls that produce no chat messages** (title generation,
advisor, turn summaries) and all idle/parked time (`requires_action`,
queueing).

The definition is documented as `COMMENT ON COLUMN
chat_messages.runtime_ms` (migration 000551, surfacing as a Go doc
comment on `ChatMessage.RuntimeMs`), on
`chatloop.PersistedStep.Runtime`, in the chatd architecture doc, and in
the Spend Management docs page.

## Index for the hourly scan

None needed: `GetTotalChatMessageRuntimeMsInRange` (#27312) filters an
hour-wide `created_at` range, which the existing
`idx_chat_messages_created_at` b-tree already serves; the residual
`runtime_ms IS NOT NULL` filter applies to one hour of rows. A partial
index would add permanent write amplification for a query that runs once
an hour.

> [!NOTE]
> Migration 000551 is also claimed by #27312; whichever merges second
renumbers via `fix_migration_numbers.sh`.

## Tests

- End-to-end: the existing full-server generation test now asserts
`RuntimeMs.Valid` on the committed assistant row (it previously read
`.Int64` without checking `.Valid`, so it passed on NULL).
- Interrupted turn: full task-level test (real DB, mock clock) asserting
the partial assistant message persists the attempt's runtime.
- Errored stream: asserts a failed invocation yields no step and no
runtime.
- Tool-using turn: asserts runtime lands on the assistant row only and
tool rows stay NULL.
- Compaction: asserts the summarization call duration is recorded and
lands on the compaction assistant message only.
- `messagepartbuffer.EpisodeDuration` unit coverage.

Ethan 0ac23e3ee1 feat: add per-template Coder Agents access control (#27285)
Relates to CODAGT-713

Depends on #27284

This makes the per-template `agents_allowed` field authoritative in the API and chatd. It adds optional create and metadata update fields with the intended default and omission semantics, supports `agents-allowed:` template search, includes the value in telemetry, and makes `list_templates`, `read_template`, and `create_workspace` read the template row directly. Existing-workspace retries remain idempotent, and blocked same-organisation templates return an actionable message.

The experimental `/template-allowlist` routes remain temporarily because the shipped AI Settings page still calls them, but they no longer control chatd enforcement. #27514 moves that page to per-template metadata, #27515 removes the legacy storage, routes, SDK types, and utility, #27517 adds the CLI flags, and #27518 updates the platform controls documentation for the per-template model, directly addressing CRF-5 and CRF-6. The stack is intended to merge as a unit.

Michael Suchacz 4b9880afa6 feat: add --chat-hook-allow-insecure to allow plain HTTP chat hook URLs (#27896)
Adds a hidden `--chat-hook-allow-insecure` /
`CODER_CHAT_HOOK_ALLOW_INSECURE` deployment option (default `false`)
that allows the chat lifecycle hook URL to use plain HTTP for any host.

The HTTPS requirement is enforced at two points, and the flag relaxes
both: `DeploymentValues.Validate()` rejects `http` hook URLs at startup,
and the hook dispatcher's `validateHookURL` allows `http` only for
loopback hosts. With the flag set, any-host `http` is accepted; the
host, fragment/userinfo, secret, and timeout checks are unchanged, and
non-http(s) schemes still fail. This removes the need for an HTTPS
reverse proxy when testing a hook consumer on a trusted network.

Following security review feedback, the flag description and docs state
that plain HTTP lets an on-path attacker forge hook responses (which
control agent execution), and `coder server` logs a startup warning
(with a redacted hook URL) when hooks run over plain HTTP.

Docs, generated API types, and the server config golden are updated
accordingly.
